Soldiers in Mexico have uncovered a mass grave containing at least 38 bodies in the northern state of Nuevo Leon.
Investigators believe drug gangs used the remote spot to torture and execute their victims.
This is the third such grave discovered in the area in the past few weeks reports the BBC.
Security forces say an anonymous tip-off led them to the site almost the size of a football pitch.
More than 24,800 people have died in drug related violence in Mexico since the government launched a crackdown in December 2006.
